BURNER.

Application mea January 27, 1926. seria No. 84,212.

My present invention has reference to a hydro-carbon burner, and particularly to a means for vaporizing the oil and to cause a mixing of air with such vapor to obtain a perfect combustion of the fuel.

' invention consists in the improvement as hereinafter described and definitely claimed.

In the drawings:

Figure 1 is a top plan view of a distillate oil burner in accordance with my invention.

Figure 2 is a side elevation.

Figure 3 is a sectional view on the line 3-3 of Figure 1. i

Figure 4 is a top plan view of the center or dome member of the improvement.

Figure 5 is a bottom plan view` of the outer or crown lmember of the improvement.

Figure 6 is a perspective view of the cross bar employed. l

The base 1 of my improved hydro-carbon burner has an outer continuous flange 2 and a lower continuous flange' 3 which is disposed inwardly with respect to the outer flange 2. The flange 3 is designed to rest on a grate of a stove in which the burner is arranged, and in this connection it may be well to state that the improvement is designed for both heating and cooking purposes.

The base 1 has a central rounded opening 4 therethrough that is surrounded by an upstanding flange 5. Resting on the base, inward of the flange 5, there are the spaced legs 6 formed on the outer face of an annular flange 7 of the intermediate or dome member 8 of the improvement. The cross sectionally rounded top of the member 8 has its outer face, at points radiating from its center, formed with depressions 9 that provide oil conduits, and the said center of the member 8 has a ythreaded opening ther through that is surrounded by an vinner flange 10. Screwed through the ment-ioned opening there is an oil jet nipple 11. rlhe nipple 11 has a restricted bore therethrough. This nipple is screwed on one end of a T 12, the lower passage in the T being closed by a threaded plug 13 .and screwed on this plug-there'is a centrallythreaded portion 14 of a cross bar 15. As shown in Figure 3 of the drawings, the cross bar has its ends contacting with the outer or lower face of the base 1, and by an arrangement as above described it will be noted that the nipple is effectively sustained on the Vintermediate member 8 and that the dome member is likewise Screwed in the lateral branch of the T- coupling 12 there is an oil conductor pipe 16. The outer end of this pipe restsV on the flange 2 of the base and the'said pipe is designed to have screwed thereon a suitable coupling for a pipev which isconnected effectively sustained on the base-- with a supply of oil, and the passage through which pipe is, of course', valve controlled.

The oil jet nipple-11'iseXtendeda suitable dista-nce above the top ofthe member 8, and 'the said member 8 has the flanged portion 7l thereof, on its upper or outer face, formed wit-h equidistantly spaced preferably rightangularly arranged lugs 17. Ther outer or crown member of the improvement is indicated bythe numeral 18, and is formed'at its open end with an outstanding" continuous flangef19, the said-flange at equidistantly spaced intervals being provided with radially disposednotches ordepressions 2O similar in number to the lugs-17.l The flange 19 Y has an outer depending lip portion 21 and has its rounded top formed with a hollow frusto conical eXtension22 in which the end of the nipple 11 is received.

The base 1, between the flanges 2 and 5 thereof, provides an oil pen. Air is admitted through the bottom of the burner through the opening 4 and air is likewise admitted into the hollow member 8 through the spaces between the legs 6 thereof. The oil in the pan is first ignited to heat the fuel conducted through the pipe 16 and to likewise heat the fuel in its passage through the nipple 11. rlhe space between the crown member 18 and the central member 8 serves as a retort and a storage chamber for the vapori'zed fuel and combustion is initiated adjacent the lip 21 of the flange or ring 19. By providing the outer or crown member 18 with the notches or depressions 2O and the intermediate member 8 with the lugs 17 the space between the confronting or contacting portions of these members is regulated. This enables the chamber between the dome and the intermediate member to be reduced or enlarged. lVhen these Vmembers are close togetherthe burner will generate onY less oil than when the members are spaced away Vportion ofthe member 8 into the pan 25,

which, as heretofore stated, is provided by the burner l between the lflanges 2 and 5.

l The simplicity of my improvement and the advantages thereof, will, it is believed, be perfectly apparent to those skilled inthe art to which such invention relates, when the foregoing description is `carefully read in connect-ion with the accompanying drawings'. Having described the invention, I claim 1.AVhydro-carbon burner', comprising a base having acentral opening therethrough which is surrounded 'by an upstanding flange yand whichbase has an upstanding outer flange providing an olil pan between said flanges, said base having its under face formed with a' continuous depending flange, a dome-shaped member having depending legs arranged in and resting on the pan, a crown" member arranged over the central member and having a central hollow frusto conical extension. means between the crown and centraly member for raising the former on the latterto regulate the spacev therebetween, an oil jet nipple screwed through the central member and having its end received in the Vfrusto conical extension of the outer member, a T coupling screwed to the inner end of the nipple, a threaded plug closing `the outer passage through the coupling, a cross bar screwed on the plug and. contactingthe under face of the base andV a fuel conducting pipe connected with the lateral branch of the T-coupling.

2. A hydro-carbon burner, including a base having an outer continuous upstaiiding flange, a central opening surrounded by an upstanding flange and a lower depending flange between the upstanding flanges, said `first mentioned flanges providing an' oil pan therebetween, a central hollow fiusto conical member having an extending flange formed with depending feet which are received in and rest on' the pan, said member having radiallydisposed grooves providing` oil conduits directed from the center to the upper face thereof, the upper face of the flange of the said central member being formed with e uidistantl f s aced unstandin(T lues.

l' p l n c .an oil jet nipple screwed through the vtop of the said member, a. T-cou-pling in which the e nipple is screwed, a threaded plug closingV the lower passage AAthrough lthe T-coupling, across bar threaded on th-e plug and' contacting the under face ofthe base, an oil conducting pipe screwed inthe lateral branch of the Tecoupling, an outer crown member having an inner continuous flange, formed with a beaded edge, said flange havingequidistantly spaced notches designed toy receive the lugs thereini'when the crown member is to be arrangedvclose to the central member and the said flange .designed to rest directly on the lugs when the crown member is `to be spaced `away from :the intermediate ineinbeix and said crown member having a rinato conical extension in which the Vouter end of the nipple 21s received.

In testimony whereof l affix my signature.
